Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic key lending device suitable for use in unattended key lending.

Traditionally, room keys at accommodation facilities such as hotels and inns, and keys for use of facilities at amusement facilities are handed over by managers who hand the keys to users. It was considered a must.

In view of this, the present invention has been made with the purpose of providing an automatic key lending device that can automatically lend keys without having to manually hand them over, and also enables unmanned management. .

In order to achieve the above object, the present invention pivots a cradle that slidably supports a key holder to a support body so as to be tiltable back and forth,
This cradle is normally held in a backward tilted position by a permanent magnet to support the key holder, and when the key throw switch is turned on, the magnetic force of the permanent magnet is instantaneously extinguished, and the cradle is held by the weight of the key. The key is tilted forward and the key is slid down into the key ejection section.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

Fig. 1 shows the external appearance of an example of the overall configuration of an automatic key lending machine incorporating the device of the present invention, Fig. 2 shows a side view of an embodiment of the device of the present invention, Fig. 3 shows the same plane, and Fig. 4 1 and 2 respectively show examples of magnetic force extinguishing means.

As shown in FIG. 2, the automatic key lending device 1 according to the present invention has a base 4a of the support 4 attached to the fixing member 3 of the automatic key lending device 2.
is fixed by setscrews 5, 5, and a prismatic key holder 6 is placed longitudinally on the upper tip of the support 4. A pedestal 7, which has a U-shaped cross section with an open top surface, is tilted back and forth by a shaft 8. It is freely supported.

The pivot position of the pedestal 7 is such that when the key holder 6 is not placed on the pedestal 7, the center of gravity is rearward of the axis 8 (to the right in the figure) so that the key holder 6 is tilted backwards (the state shown in the first figure). When the key holder 6 is placed on the shaft 8, the key holder 6 is tilted toward the front (to the left in the figure) of the shaft 8.

A permanent magnet body 9 is located at a position where the lower surface of the pedestal 7 comes into contact when the pedestal 7 is tilted rearward under no load.
is provided on the support body 4.

The permanent magnet body 9 is wound with a toroidal coil 10 as shown in FIG. 4, and is energized when a key throw switch (not shown) is turned on to generate a magnetic force in a direction that cancels the magnetic force of the permanent magnet body 9. It is formed so that the suction of the pedestal 7 is released.

Note that the magnetic field generated by the toroidal coil 10 is sufficient if the magnetic force of the permanent magnet body 9 is weaker than the force that can cause the pedestal 7 to tilt forward due to the weight of the key holder 6, so the magnetic field of the permanent magnet body 9 can be completely reduced to zero. It's fine.

Further, the pedestal 7 may be formed entirely of a magnetic material, but it may also be formed of a non-magnetic material such as synthetic resin, with the magnetic material buried only in the portion corresponding to the permanent magnet 9. good.

The support body 4 is provided with a display switch 11, and the actuating piece 12 of this switch 11 projects from a hole 13 formed in the bottom surface 7a of the pedestal 7 to the top surface thereof, as shown in FIG. When the key holder 6 is placed, it is pushed in and the switch 11 is turned on.

The automatic key lending device 1 having the above configuration is incorporated into an automatic key lending machine 2 of a hotel, as illustrated in FIG.

This automatic key lending machine 2 displays, for example, photos 14° 14... of each room of the hotel on its front, and an automatic key lending device 1 corresponding to each of these rooms is installed inside the machine. Key ejection switch activation buttons 15, 15, . . . are arranged corresponding to the automatic key lending device 1.

Then, look at the photos of the rooms above, select the one you like, and press the button 15 for operating the key throw switch corresponding to that room.
By pressing one of the keys 15, .

In addition, an illumination lamp is placed on the back of the photo 14. The lights in the corresponding room photo may be turned off to indicate that the key for that room is in use.

Next, the operation of the above embodiment of the automatic key lending device according to the present invention will be explained.

Before the key is thrown out, the rear end of the pedestal 7 is attracted to the permanent magnet 9 and tilted backwards, as shown in FIG. 2, and the key holder 6 placed on this is stably held. At the same time, since the operating piece 12 of the display switch 11 is pushed in by the key holder 6, the lighting lamp in the photo 14 of the corresponding room lights up, indicating that the room is vacant. .

Now, when the key throw switch is turned on, the toroidal coil 10 is energized to generate a magnetic force in the opposite direction to the lines of magnetic force of the permanent magnet 9, canceling the magnetic force of the permanent magnet 9 and eliminating the attraction force.

As a result, the pedestal 7, which had been attracted and held by the permanent magnet 9, swings to a forward tilted position as shown by the chain line in FIG. The key is ejected into the key ejection port 16.

At the stage when the key holder 6 falls from the pedestal 7, the power to the toroidal coil 10 is cut off, and at the same time as the key holder 6 falls, the weight balance of the pedestal 7 is lost and the pedestal 7 swings backward. The rear end is again attracted to the permanent magnet 9 to maintain the backward tilted posture.

Also, after the key holder 6 falls, the display switch 1
1 can protrude from the hole 13 of the pedestal 7 onto the bottom plate 7a, so that the switch 11 remains open and thus the illumination of the photograph 14 representing the room corresponding to the automatic lending device 1 The lamp remains off to indicate that the room is in use.

Note that the above display can also be made by simply lighting the lamps without using the photographs 14, 14, . . . .

In this way, the present invention provides a pedestal that slidably supports the key holder so that it can swing freely like a seesaw, and maintains the state in which the key holder is placed by the attraction of the permanent magnet.
When the key ejection command is issued, the magnetic force of the permanent magnet body is instantaneously extinguished, and the key holder is tilted forward using the weight of the key holder, allowing the key to slide into the key ejection slot and be ejected, so that when the key is not in use, While it is stored, its state is maintained by a permanent magnet, so there is no need to use any electricity, and only a momentary energization is required when the key is ejected. Compared to this type of equipment, it only takes about a spring, and management costs are significantly reduced.

Furthermore, since there is no need for manual intervention in handing over the keys, the administrator's labor is reduced, greatly contributing to labor savings.

Furthermore, since the key is held using the slope of the cradle, there is no need for any special holding mechanism to actively hold the key or key holder, which makes the device extremely simple and can hold a large number of keys. The overall structure of the loaner machine to be handled can be significantly reduced, and various excellent effects can be obtained, such as the ability to make the loaner machine inexpensive and free of breakdowns.

Although this embodiment is described as a key lending device with a key holder, it can be applied to other devices similar to this, and is not limited to this embodiment. It's not something you can do.
